I've run with a bad MAF.  I've also run with it unplugged.  What  
power there is I would hardly call performance.  At the very best, it  
crawls.  Putting a new MAF on it is the only real answer.  I've also  
heard tons of horror stories about using the 2.0 MAF in place of the  
TDI one.  I've heard everything from 'it works great!' to 'I'm  
smoking like a chimney!'  Basically, it's best to just get the right  

They have remanufactured TDI MAF's all over the place for $80.  I  
purchased my last one at the dealer for $144.  It was a new revision,  
and had added protection for the sensor.  It looked like it just  
might hold up a little longer than the older ones do.  We'll see.  In  
any case, I have a 12 month warranty on it, so it should fail in  
precisely 366 days.

Once you replace the MAF, the car starts feeling like a rocket.  It's  
amazing how different it is when the parts are actually working right.

There's my two pennies on the subject.  Get the right part for the  
right job.
